FARR does not search all of your partitions. Default setting is to search your My Documents folder, Start menu, desktop etc... You can add additional folders to the search by opening Settings -> Search Folders. You'll see a list of folders that are set by default. You can add folders of your choosing, change order of search by drag and drop etc.

However, FARR is not designed to search your entire partitions or hard drive. Because of the index-less design FARR is slow on searching your entire disk. There is a plugin that can help you index your entire hard drive and quickly find files anywhere. More details here.

Although, you can navigate your entire disk by default, using "File browsing mode". Basically you just type c:\ into farr, and it gives you a list of files and folders inside C:\. You than navigate into folders by pressing tab, and filter the results by typing in more keys.

There is more on all of this in the help file provided.
